I love my Tilley T1, but I think they're out of production.
I tried to replace it in the off season with a Filson Summer Packer Hat because the Tilley shrank a bit and is now just slightly too tight, but it didn't take. The Filson does the same thing that boonie hats do for me...the brim is too soft and tends to flip either up (giving my no sun/glare protection) or worse, down (blocking my vision.)
Nothing I've tried beats the Tilley. Mine is a little tight and is pretty rough looking at this point, but I'm going to keep wearing it until it falls apart, which might not be for another decade.
This was my assessment when I got the Filson: Sailing Hats | Sailing Fortuitous
